Ashwagandha (Withania somnifera)

Tribulus (Tribulus terrestris)

About

Ashwagandha (Withania somnifera), sometimes called “Indian ginseng,” is a sturdy shrub growing to about 5 ft (1.5 m) with oval leaves, greenish or yellow flowers, and small, round fruits. NCCIH says some preparations may help insomnia and stress, but there isn't enough evidence to know whether it helps most other conditions.

The fruit of the plant is the primary medicinal part used.

Liver: Liver injury linked to ashwagandha supplements is rare but has been reported (NCCIH), and LiverTox places it in its likely-cause category (B). Stop and seek advice if you notice yellowing skin or eyes, dark urine or itching. Pregnancy & Breastfeeding: NCCIH says to avoid it during pregnancy and not to use it while breastfeeding. Thyroid: ODS notes it might affect thyroid function. Nightshade Sensitivity: This herb can cause adverse reactions in those sensitive to the nightshade family. Digestive Sensitivities: Some individuals may find it hard to digest ashwagandha.

Consult a healthcare provider before use, especially if taking hormone-related medications or if you have hormone-sensitive conditions.
